Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
Anker 521 PowerHouse costs $950 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 1500 Ultra holds 500% more energy (1536Wh vs 256Wh), so it runs the same load proportionally longer.
- Jackery Explorer 1500 Ultra has 3300W more surge headroom (3600W vs 300W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 521 PowerHouse is 18.3 lb lighter (8.2 lb vs 26.5 lb).
- Jackery Explorer 1500 Ultra is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Jackery Explorer 1500 Ultra
The portability record-holder: 1536Wh at 26.5 lb, lighter than most 1kWh units. You pay $200 over the 1500 v2 for that weight saving.
Best for: Van lifers and overlanders where every pound is negotiated.
Where it falls short:
- 1800W output is lower than the cheaper 1500 v2's 2000W
- $1199 is a premium for weight alone
Anker 521 PowerHouse
A pocket-scale LiFePO4 unit for keeping devices alive. 200W of output means it's a charger, not an appliance station.
Best for: Travelers and campers topping up phones, cameras and a laptop.
Where it falls short:
- 200W output runs devices only
- 256Wh is small
